Absans Epilepsi Patofizyolojisinde Netrin-1’in Yeri

Year 2016, Volume: 7 Issue: 25, - , 30.03.2016

Abstract

Amaç: Netrin-1 proteininin embriyonik gelişim boyunca akson yöneliminde ve hücre göçünde etkin rol oynadığı bilinmektedir. Ayrıca netrinin epilepsi patofizyolojisinde anormal sinaps gelişimi ve nöron göçüne katılabileceği de gösterilmiştir. Ancak absans epilepsinin gelişim sürecindeki etkisi henüz bilinmemektedir. Bu çalışmada Wistar Albino Glaxo/Rijswijk (WAG/Rij) sıçanların korteks ve talamus dokularındaki netrin ekspresyon düzeylerinin saptanması amaçlanmıştır.

Gereç ve Yöntem: Çalışmada genetik absans epilepsili 2 ve 6 aylık erkek WAG/Rij sıçanlar (n=14) ile epileptik olmayan 2 aylık ve 6 aylık erkek Wistar kontrol sıçanlar (n=14) kullanıldı. Anestezi altında dekapite edilen tüm sıçanların korteks ve talamus dokuları izole edildi. Gruplar arasındaki netrin-1 ekspresyonunun düzeyi standart teknikler kullanılarak Western Blot yöntemiyle tayin edildi ve dansiteler arasındaki farklar gruplar arasında karşılaştırıldı.

Bulgular: Elde edilen verilere göre; absans epilepsili WAG/Rij sıçanlar ile epileptik olmayan Wistar sıçanların beyin korteks ve talamus bölgelerinde netrin-1 ekspresyonu saptanmamıştır.

Sonuç: Bu çalışma, netrin-1 ekspresyonunun absans epilepsideki etkisinin Western Blot yöntemiyle araştırıldığı ilk çalışmadır. Elde edilen bulgulardan yola çıkılarak moleküler ve histolojik yöntemleri içeren kapsamlı çalışmalar planlanmalı, deneysel olarak elde edilen netrin-1 bulguları konfirme edilmelidir.
